Specification of Letters Patent.

Patented Nov.- 4, 1913.

Application filed November 7, 1910'. Serial No. 591,075.

To aZZ whom it may concern:

Be it known that I, Mum IN V. Mormii'oosn, of the borough of Brooklyn, county of Kings, and State of New York, a citizen of the United States, have inventeda new and useful Improvement in Line-Casting Machines, of which the following is a specification.

My invention relates to line casting machines wherein two sets or fonts of matrices, differentiated in form at their lower ends, by notches or otherwise, are employed in connection with a corresponding number of magazines.

The object of the invention is to provide means whereby matrices which commonly pass through the lower distributer to the lower magazine may be caused, when required, to travel through the upper distributer into the upper magazine.

The invention may be considered an improvement on the mechanism shown in Letters Patent of the United States Nos. 640,033 and 767,169.

In the latter patent a bridge or detector is arranged in advance of the distributer, and in the path pursued by all the matrices. Matrices without notches in their lower ends ride upon the bridge and are sustained thereby at such a level that they are de livered to the upper distributer bar; while matrices which have notches in their lower ends straddle the bridge, without being supported thereby, so that they may pass forward at a low level to the lower distributer bar.

Instead of making the bridge a solid, immovable member, as heretofore, I now divide it vertically in the middle and provide for the lateral separation of its parts, so that its members will lie beyond or outside of the notches in the advance of the matrices, and serve to support such matrices at the higher level, in order that they may pass to the upper instead of to the lower distributer.

lVith the exception of the parts herein shown and described, the machine may be in all respects of the ordinary construction.

In the drawings: Figure 1 1s a vertical cross-section of the mechanism shown in Patent 767,169, with my improvement embodied therein, the two parts of the bridge being separated or spread apart, in order to sustain the notched matrices at the upper level. Fig. 2 is a similar view showing the parts of the bridge closed together in order that it may operate in the same manner as in the above named patent, and permit the notched matrices to advance at the lower level. Fig. 3 is a side elevation of the bridge.

Referring to the drawings, A A represent the ordinary Mergenthaler matrices such as are now in common use, each with a notch, a, in its lower end. The composed line of these matrices is supported and advanced endwise in the usual manner.

B represents the bridge forming the subject of the present invention. It consists of two complementary parts, I) and b, mounted on a right and left hand screw C, which is supported at its ends on the stationary bars D, forming part of the usual mechanism, so that the rotation of the screw will serve to separate the parts equally from the center line, as shown in Fig. l, or to draw them together, as shown in Fig. 2.

The parts 6 and b are provided at their upper sides with upwardly extending lips, and 5 When the parts are closed together as shown in Fig. 2 these lips constitute in effect a single lip or bridge adapted to pass through notch, a, of the advancing matrix without effect thereon. In this position of the parts they operate in the same manner as those represented in Patent 767,169. hen, however, the two members are separated as in Fig. 1 the lips b and will stand outside of, or beyond, the notch in the advancing matrix, and acting on the lower ends of the matrix, will serve to sustain the same at a higher level, in order that it may pass forward to the upper distributor bar X. In other words, the expanded bridge serves to carry the notched matrices at the upper level in the same manner that matrices without notches are sustained in the patented structure.

The advantage of the device lies in the fact that the machine may be adapted at will to carry any given font of matrices in the upper magazine, that is, to permit the use of a magazine containing a given font of matrices in the upper position on the machine without removing or disturbing the lower magazine.

The screw O has its end journaled in the supporting bar D so that it cannot move endwise, and it is provided at one end with a notched lip, 0, adapted to receive a screw driver, or otherwise formed in such manner that it may be readily turned by a suitable instrument, or by hand.

The invention consists broadly in a matrix bridge or distinguisher which may be varied in form, or in the relation of its parts, so that it may be changed in form and adapted to permit the passage of the same matrices in one path or another as required.

It is manifest that the matrices belonging to the two fonts may be differentiated in form in any suitable manner, and that the operative portions of the bridge may be modified to correspond;

Having described my invention, what I claim is:

1. In a distributing mechanism, a matrix sustaining bridge to deliver matrices at different levels and comprising two members, one movable relatively to the other, and adapted to be set in different relative positions.

2. In a distributing mechanism, a matrix sustaining bridge to deliver matrices at different levels and comprising a plurality of members, one adjustable relatively to the other, and means for maintaining said member in its adjusted position.

3. A matrix sustaining bridge to deliver matrices at different levels and comprising a plurality of members, and means for adjusting one of said members toward and from the other and for maintaining it in its ad usted positlon.

4. A matrix sustalning bridge comprising two members, and means for adjusting them equally in reverse directions and for maintaining them in their adjusted positions.

5. In a line casting machine, the combination of notched matrices, and a bridge or detector comprising two members, relatively movable in order that they may act within Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents. Washington, D. O.
